"He made room in my electrical panel by installing double circuit-breakers to accommodate my home. Based on the work and how they presented themselves, I would recommend them. Very clean and professional, and I would hire them again in a heartbeat. Their price was reasonable, the work was great, and it was an overall pleasant experience."

"Chris called and came over right away to give us an assessment of the project and the price for installing a new electrical panel. Fair price, superior work. He was flexible/accommodating to fit our job in quickly since we were going on vacation shortly. The day of the job, Chris stayed till late evening to complete the job. We are completely satisfied. His work is meticulous and neat. Chris is professional, experienced, excellent at his work, and very personable. Would not hesitate to recommend him to all."

"They were extremely honest, courteous, need and fair. We had them install all of the electric for my pool equipment, lights etc. and run electric to the dock for boat power. They were so good, we had them come back and re run all the electrical in the downstairs of our house including new outlets, lights etc. we also had them upgrade our panel to a 200 amp. I can not say enough about how clean and easy they were to work withâ ¦.I would recommend them 100%!"

"i recently had a tesla charger installed, and i am extremely satisfied with the service. the electrician did an outstanding job he was professional, knowledgeable, and completed the installation much faster than i expected while maintaining excellent quality. the work was clean, efficient, and everything was installed perfectly. on top of that, his pricing was very reasonable compared to other estimates i received. it’s not often you find someone who delivers great workmanship, works efficiently, and offers affordable rates. i highly recommend him to anyone needing electrical work or an ev charger installation."

Generator Install questions, answered by experts

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.
